Terminal Jumper

A circuit board P30 jumper is set based on alternator
type—Wound Field
Fast Response (less than 350 kW). The jumper is
factory set and needs no further adjustment.

Fuses

AC Circuit Fuses (TB5). Fuses are located inside the
generator set control box. See Figure 1-7
1.5-Amp (V7) fuse protects L1 sensing input to
D
interconnection circuit board.
1.5-Amp (V8) fuse protects L2 sensing input to
D
interconnection circuit board.
1.5-Amp (V9) fuse protects L3 sensing input to
D
interconnection circuit board.
DC Circuit Fuses are located on the controller circuit
board. See Figure 1-8.
1-Amp (F1) auto-resettable, fuse protects the
D
controller circuits.
1-Amp (F2) auto-resettable fuse protects the
D
controller circuits.
12-Amp (F3) non-replaceable fuse protects the
D
engine/starting circuitry and accessories.
